Although not shown specifically, the conventional glove box is pivotally supported in the space of the instrument panel of the automobile, and when not in use, it is rotated to the space side and locked in its closed position. At the time of use, the lock is released, and it is configured so that an object can be taken in and out by rotating to an open position (see, for example, Patent Document 1).
JP 2004-262334 A

  However, when locking to the closed position under the conventional glove box, the lid of the glove box must be pushed completely into the void side of the instrument panel, so the load for the lock is also added, It was hard to close, and I had a dislike of lack of luxury.

  The present invention has been developed in view of such circumstances, and the invention according to claim 1 includes a support body or a storage body supported by the support body, and a lid that opens and closes an opening of the support body or the storage body. In a storage device that is pivotally supported, an arm member protrudes in the vicinity of the shaft support portion on the rear surface of the lid, and an arm pin is supported at the tip of the arm member so as to be movable in the longitudinal direction of the arm member. Alternatively, a cam member is rotatably attached to the storage body supported by the support body, a spring member having a dead point is attached to the cam member, and an arm pin is fitted on the side of the cam member facing the arm pin. When the arm is inserted into the first groove when the lid is rotated from the open position to the closed position by forming one groove, the cam member is rotated by the spring pressure of the spring member exceeding the dead point. Wherein the pull on the support or housing side via the arm member.

  According to a second aspect of the present invention, on the premise of the first aspect, an emergency second groove into which an arm pin is fitted is formed in the cam member.

  The invention described in claim 3 is based on claims 1 and 2, wherein the cam member and the spring member are built in a case having a copying surface of an arm pin, and the case is fixed to the support body or the housing body side. It is characterized by.

  According to a fourth aspect of the present invention, on the premise of the third aspect, the copying surface of the case has a curved surface shape along the rotation locus of the arm pin.

  Therefore, according to the first aspect of the present invention, when the arm pin is fitted into the first groove of the cam member when the lid is rotated from the open position to the closed position, the spring member is over the dead point. Since the lid is automatically pulled to the support or storage body via the arm member, the lid is spring-loaded even if the lid is not completely pushed into the support or storage as in the prior art. It can be rotated to the closed position only by the spring pressure of the member, and accordingly, a high-class feeling at the time of operation is greatly obtained.

  In the invention according to claim 2, in an emergency, that is, when the cam member is not rotated to the normal standby position for some reason even though the lid is rotated to the open position, When the lid is rotated in the closing direction, the arm pin is now inserted into the second groove of the cam member. In this state, when the lid is rotated in the opening direction, the cam member can be returned to a normal standby state. Therefore, the cam member can be prevented from being damaged by an emergency and can be continuously reused without causing trouble to the user.

  In the invention of claim 3, since the cam member and the spring member are built in the case and the case is fixed to the support body or the housing body side, the assembly is facilitated by unitization and the arm pin is attached to the case. Since it can be inserted into the first groove while being guided along the copying surface, a reliable operation can be obtained. In addition to this, manufacturing and assembly variations can be effectively absorbed by the movement of the arm pin guided by the copying surface.

  In the invention according to claim 4, since the copying surface of the case has a curved surface shape, it is constant after the arm pin is first actuated, so that the arm pin is not actuated more than necessary. The durability of can be improved.

  The present invention is based on the premise of a storage device that pivotally supports a support body or a storage body supported by the support body and a lid that opens and closes the opening of the support body or the storage body, and closes the lid from the open position. When the arm pin supported by the arm member is inserted into the first groove of the cam member when rotating to the position, the cam member is rotated by the spring pressure of the spring member exceeding the dead point, and the lid is interposed via the arm member. Thus, it is intended to obtain a high-class feeling at the time of operation by automatically pulling it toward the support or the storage body.

  Hereinafter, if the present invention is described in detail based on a preferred embodiment illustrated, the storage device according to the embodiment is intended for a glove box provided in an instrument panel of an automobile, but its basic structure 1 to 3, a glove box body B as a storage body is fixed to an instrument panel (not shown) side as a support, and an opening of the glove box body B is formed below the glove box body B. It is assumed that the lower part of the lid L that opens and closes is pivotally supported via the shaft 1. In this case, it is also possible to define the glove box body B by the instrument panel itself without forming the glove box body B separately.

  Therefore, specifically, as shown in FIG. 4, the mounting portion 2 is integrally bulged in the vicinity of the shaft support portion on the one side edge of the rear surface, and then bulged toward the lid L side. A slide having an angular pin-shaped arm member 3 having a pair of guide grooves 4 formed at the tip thereof on the mounting portion 2 and having an arm pin 6 that slides inside the guide groove 4 inside the arm member 3. A configuration is adopted in which the member 5 is supported so as to be movable in the longitudinal direction, and the slide member 5 having the arm pin 6 is elastically biased toward the distal end portion of the arm member 3 by the compression coil spring 7.

  For the glove box body B, a cam member 8 is rotatably attached to a side surface corresponding to the arm member 3 and a tension coil spring 9 as a spring member having a dead point is provided on the cam member 8. At this time, the cam member 8 and the tension coil spring 9 are housed in a separately molded case 10, and the case 10 is attached to the side surface of the glove box body B using its mounting hole. A fixed configuration is adopted. Therefore, in this case, since it can be unitized, the assembling work becomes easy.

  As shown in FIG. 5, the case 10 is formed with a copying surface 11 having a curved surface along the movement locus of the arm pin 6 on the front side thereof, and can move to the arm member 3 when the lid L rotates. The arm pin 6 supported by the guide is guided while being elastically contacted with the copying surface 11, and a bearing hole portion 12 is formed on the front and back surfaces thereof, and the other end portion of the tension coil spring 9 is hooked inside. A boss portion 13 is formed.

Further, the cam member 8 is formed in a substantially rectangular shape, and a shaft portion 14 that engages with the bearing hole portion 12 of the case 10 is formed on the front and back surfaces of the center, and each shaft portion 14 is formed in the bearing hole of the case 10. By being engaged with the portion 12, the glove box body B is rotatably supported on the glove box body B, but the notch-shaped first groove 15 into which the arm pin 6 is fitted and the first groove 15 on the side facing the arm pin 6. The two grooves 16 are formed at regular intervals, and a boss portion 17 that hooks one end portion of the tension coil spring 9 is formed behind the first groove 15. The relationship between the first groove 15 and the second groove 16 is such that the first groove 15 is formed deeper than the second groove 16 and the second groove 16 is slightly inclined with respect to the first groove 15 as shown in the figure. Is set to

  The tension coil spring 9 is mounted between the cam member 8 and the case 10 to provide its own spring pressure to the cam member 8, but beyond the dead point, the cam member 8 is unidirectional. When the cam member 8 rotates, the cam member 8 is provided with a turning force in one direction. Conversely, when the cam member 8 rotates in the other direction beyond the dead point, the cam member 8 moves in the other direction. It is the structure which can provide the switching power with respect to.

  Therefore, even under the storage device having such a configuration, if the lid L is rotated to the glove box body B side and locked in the closed position, the non-use state can be obtained, similarly to the conventional case. If the lock is released and the lid L is rotated to the open position, the use state can be obtained. However, when the lid L is in the open state, as shown in FIG. The side surface in which the first groove 15 and the second groove 16 are formed is placed at a standby position with the spring pressure of the tension coil spring 9 facing the opening side of the glove box body B.

Then, when the lid L is rotated in the closing direction from the open position of the lid L shown in FIG. 1, the arm member 3 is also rotated in the same direction in conjunction with the rotation of the lid L. As shown in FIG. 2, the arm pin 6 movably supported in the guide groove 4 of the arm member 3 moves while elastically contacting the copying surface 11 of the case 10, and the arm pin 6 moves to the first groove of the cam member 8. When the cam member 8 is inserted while being reliably guided by the shaft 15, the cam member 8 rotates in the same closing direction as the arm pin 6 and exceeds the dead point of the tension coil spring 9, so that as shown in FIG. Is automatically rotated in the closing direction by the spring pressure of the compression coil spring 7, and the lid L is automatically pulled to the glove box body B side via the arm member 3.

  Therefore, in this embodiment, if the cam member 8 is rotated until it exceeds the dead point of the tension coil spring 9, the lid L is automatically moved to the glove only by the spring pressure of the tension coil spring 9. Since it will be pulled in and locked to the box main body B side, a high-class feeling in operation will be greatly obtained as compared with the conventional case.

  Incidentally, the fact that the copying surface 11 with which the arm pin 6 is elastically contacted has a curved shape is constant after the compression coil spring 7 is first contracted by the arm pin 6, so it is necessary to contract the compression coil spring 7 more than necessary. Therefore, the durability of the compression coil spring 7 can be improved and the user does not feel a spring feeling. Further, the fact that the arm pin 6 is elastically contacted with the copying surface 11 of the case 10 has an advantage that manufacturing variation and assembly variation can be effectively absorbed by the movement of the arm pin 6 and the operation of the copying surface 11.

  On the contrary, when the lock of the lid L is released and the lid L is rotated in the opening direction, the arm pin 6 fitted in the first groove 15 causes the cam member 8 to move to the spring pressure of the tension coil spring 9. However, if the cam member 8 exceeds the dead point of the tension coil spring 9 at this time, the cam member 8 is automatically released in the opening direction by the spring pressure of the tension coil spring 9. The lid L tries to push out the lid L to the open position. In this case, a braking force is applied to the rotation by the action of a damper (not shown), so as shown in FIG. The lid L slowly rotates to the open position, and there is no fear of generating an unpleasant hitting sound. In this state, it goes without saying that the cam member 8 returns to the standby position described above.

  Further, as shown in FIG. 6, when the cam member 8 is not rotated to the standby position for some reason even though the lid L is rotated to the open position as shown in FIG. When the lid L is rotated in the closing direction, the arm pin 6 cannot be fitted into the first groove 15 as shown in FIG. 7, so that the arm pin 6 is forcibly fitted into the second groove 16 of the cam member 8 this time. It will be.

Therefore, after obtaining such a state, when the lid L is rotated in the opening direction, the arm pin 6 rotates the cam member 8 against the spring pressure of the tension coil spring 9. Thereby, as shown in FIG. 1, the cam member 8 can be returned to a normal standby position. For this reason, in this embodiment, it goes without saying that the cam member 8 will not be damaged even if an emergency occurs, and in particular, it can be continuously reused without causing trouble to the user. It becomes. In this case, since the cam member 8 is pivoted in the closing direction of the lid L from the beginning, the pulling force of the lid L cannot be obtained.

  In the above embodiment, the glove box body B as the storage body is fixed to the instrument panel as the support body and only the lid L is rotated. However, the present invention is limited to this. Needless to say, the lid L and the glove box main body B are integrated, and the glove box main body B can be rotated together with the lid L.

  The storage device according to the present invention can automatically retract the lid and can provide a high-class feeling during operation. Therefore, the storage device is advantageous when used in a glove box or the like provided on the instrument panel side of an automobile.
